Convert Excel Date/time *to* Unix Timestamp |
Convert Excel Date/time *to* Unix Timestamp - Excel |
|
I've searched a lot on Google and on here and have found a ton of ways to convert a Unix timestamp *TO* an Excel Date/Time value but I need to do it the other way.
I've got 2 columns of values (about 9700 in total) - they're all in Excel Date/Time format and the cells have been formatted as such.
I need to convert all those values *TO* a Unix timestamp. For example, one of the cells has this:
25/07/2007 9:18:08 PM
Obviously that date isn't US format (I live in AU). Anyway, the Unix timestamp for that is 1185398288 (according to http://www.onlineconversion.com/unix_time.htm).
Obviously doing this manually for each cell isn't very productive.
Can anyone help me with a formula that can convert the existing Excel Date/Time *TO* a Unix timestamp?
Apologies for the emphasis but I've asked a ton of people and they all come back with how to convert the other way ...

For example: Cell A1 has a time format (hh:mm) value of 04:00; which is the Start Time. I would like cell D1 to have a text format value of "04:00" (result is dependant upon what is entered in A1). I would duplicate the same formulas to reflect Stop Times in other cells.
My final result is to have another cell (F1) use the Concatenate formula to have the Start and Stop time shown in one cell as "04:00 - 12:30". The times would change based on the Time formated values entered into the Start and Stop time cells.
I have researched this in the board and found many excellent ways to do the opposite, but not convert Time format to Text format. Any assistance is greatly appreciated.

i have a column of numbers that we extracted from a database as whole numbers. for instance, 30 should be .30 and 100 should be 1.00. when i try to increase or decrease the decimal point it doesn't allow me to convert it to those positions.
would any one have a tip of how i can easily convert this? there are over 2000 entries in my excel spreadsheet so to do it manually would take a lot of time/effort.
thank you!
format/cells/number from the category list. But it won't take, and stays
text-like. Any ideas?
would really appreciate anyones help with this.
I have a column full of text-formatted fractions...
4/5
6/4
3/1
2/5
4/5
etc, etc.....the column is very long!!
I need to convert these to actual fractions...ones I can add to equations, allowing me to multiply and add.
If I highlight the column and goto "format Cells" and change to fraction, the values still stay in the left of the cell.....its only when I manually click on each individual cell, then tick the little green tick, does the cell validate, and the value in the cell moves to the right (and is therefore a proper value).....problem is I have to keep doing this for each individual cell.....and I have 70000+ cells in this column!
Any suggestions on how I could speed this up?
thanks
Is there a way to enter a colon into a standard number to create a value that can be formatted into a 24 hour time value ?
eg a time is listed as 1345 with a general number format, and I want it returned as 13:45 witha custom format of hh:mm.
Other than creating a table and using a vlookup function, I am hoping there is a better way?

inbetween the two dates. Does anyone know how to then convert the number of
days into months?
I made a simple worksheet that we have been manually entering the time for employees, but there are too many errors (even with simple math). Can someone help me convert the time of ex: written 8-4:30 or 10-3 (meaning 8:00am to 4:30pm) where you have the total weekly hours? Right now I have a column for overtime. Is there a way to automatically calculate the over time also? The work day is 8-4:30 with a half hour lunch (lunch is not calculated into the hours, so you minus a half hour). 8-4:30 equals 8 hours. So, if a person works 8am to 6:30pm, how can I set it up where in the first row of time, I will type in 8-6:30pm. In the totals column to the far right, it will display 8 hours. In the (O.T.) column, it will display 2 hours.
This way, when I call in my payroll, I will have the total "regular" hours in one row and underneath, I will have the total overtime hours.
Or... does anyone have a better solution to keeping track of their hours?
Thanks!

So I am at work workin on this report and I need a function that will make Excel automatically insert the today's date in a cell (let's say D90) when I fill the content of another cell (for example C90) and the that will be inserted will never change. I tried to use the =TODAY( ) function but it keeps updating the date in the cell to the current date if i reopen the worksheet 2 days later. I need the cell to keep in the cell the date of the day when I filled in the content of cell C90 and do not updated it every time i open the document to the actual date.. Thanks in advance!!
But I do not want to insert any sheet for different dates & also the format will not be copied & paste in the same sheet. Just at the place of Date the date will be changed & the datas will be entered manually for each day.
In future, when I shall put the date, the datas will show that particular date's datas only.
Can anyone help me ?
current date when opened, using today(). Users then Save As to have an
archive copy of their spreadsheet. However, when they go back to access
their saved sheet, the date changes from the created date to the current
date. How do I stop this in Excel?
I know that Word lets you do this by changing the code from {DATE} to
{CREATEDATE}, but I can't find a similar setting in Excel.
Please help and thank you!
How i can convert Hijra (Islamic) Dates into Gregorian?
a formula or VB
any help
Cell B5: start time: 4:15 formatted as 4:15:00 am
Cell B6: finish time: 6:15 formatted as 6:15:00 am
Cell B7: total time: 2:00 formula in cell: =TEXT(B6-B5,"h:mm")
Cell B8: total batches processed: 22 (this is entered manually)
Cell B9: batches per hour: formula in cell: =B8/TEXT(B7,"h")
as long as I have this formula in cell B9 the answer comes out correct which should be 11 per hour.
If the formula in B9 is B8/B7, the answer is 264.0, Is this because of the way excel is reading the total time or the total time is formatted as a time, not an actual number? Is this the correct way to solve the problem?
answer should be 11 per hour.
I have formulas to add a number of days to a cell containing an entered date and display the resulting new date (ie. 03/01/2011 (c34)+11 = 03/12/2011)
I am seeking to leave resulting formula cell blank until a date is entered in the input cell. Currently when the input cell is empty the formula cell obviously displays 1/11/1900 using the above example.
What conditional format would achieve leaving the formula cell blank until date data in entered into the source cell?
Hopefully a simpler question for your experience level than mine.
Cells accept hours over 23,
Adding cells in column returns correct total time.
Have not found a way to multiply these cells by a $ hourly rate.
So use HOUR(cell ref) and MINUTE(cell ref) to capture values in referenced
cell - then use these values to calculate total payment for $rate per hour.
However, the HOUR(cell ref) formula returns the hours in excess of 24 when
the cell contains an hour value in excess of 23 (ie 27 hours returns 3).
I hope you can help me with what I would like to do. I've searched and searched and not come up with anything yet!!
I have one sheet which is my 'data' sheet with a number of columns, one of which is a date which may be repeated.
I then want to use another sheet with two cells where two dates can be entered and a button which allows you to copy the rows of data from the data sheet which have dates between the two specified originally. The list in the data sheet may not be in date order although I could update a macro to do this for me if needed. I would also like to do it so that if "ALL" is typed in the date fields, it pulls over ALL the data. (Or something similar)
Any help you can give would be much appreciated.
Cheers,
Kevin
I am trying to reference a cell on another worksheet, the cell is formatted to be a date. when i put in the following formula =Sheet2!A1 and i don't input a date into A1 on sheet 2 the cell containing the formula shows the date 00/01/1900, is there any way of stopping this showing, ideally the cell would be blank until I inputted a date into A1 on sheet 2
Any help would be very much appreciated
Thanks in advance for any assistance.
